Wedding guests included Shevell's son Arlen, her second cousin BarbaraWalters, McCartney's brother Mike, The Beatles' RingoStarr and his wife BarbaraBach, and GeorgeHarrison's widow, Olivia. "The wedding was lovely," Walters said afterward.

During the intimate ceremony, McCartney -- who has been married twice before -- presented Shevell with a Neil Lane eternity band featuring 5-carats of square-cut diamonds set in platinum.

Following their nuptials, the newlyweds were feted at McCartney's home in St. John's Wood, where guests including The Rolling Stones' Ronnie Wood, CharleneSpiteri, JoolsHolland and Kate Moss feasted on a decadent menu that included savory tarts, vegetable gyozas and two weddings cakes -- one vegan (made with apples) and one chocolate.
